How LiST Works
The Lives Saved Tool (LiST), developed by the Institute for International Programs at Johns Hopkins Bloomberg School of Public Health and funded by the Bill & Melinda Gates Foundation, is a model that estimates the impact of scaling up health and nutrition interventions on maternal, newborn, and child health. LiST is a part of Spectrum, a software package maintained by Avenir Health. The model been used for over 10 years and is regularly updated to incorporate the latest evidence from the scientific literature and household survey data.

The LiST module produces estimates of global health impact by modeling outcomes such as:
- Neonatal and child mortality
- Maternal mortality
- Birth outcomes (preterm, small-for-gestational-age, low birth weight)
- Nutrition outcomes (stunting, wasting, anemia)
The framework of LiST is based upon:
- Demography details, either read directly from demographic projections produced by the United Nations Population Division or derived from national or subnational demographic estimates
- Cause of deathinformation for neonates, children under five, mothers, and stillbirths, from country-specific WHO profiles or estimated by using local data sources
- Coverage levels for a variety of key health interventions that affect child and maternal mortality
- Health statusindicators for a national or subnational setting
- Effectiveness estimates for neonatal, child, and maternal interventions from the latest scientific reviews and literature
The Lives Saved Tool (LiST) is part of Spectrum, an integrated suite of policy modules, and linkages between LiST and other analytic tools allow users to modify aspects including demography, HIV/AIDS programming, and family planning determinants.
The following modules are currently included in Spectrum:
To run LiST, users need to download and install Spectrum here. LiST can then be specified as a module to be activated for use in the projection.
The full list of data sources, assumptions, and citations from the scientific literature are available in the Help documentation for LiST. This can be accessed as a PDF on the Training page of our website or by clicking the “Help” button inside the software.
Most data sources are updated on an annual basis, or as frequently as nationally representative household surveys are conducted in a given country. The research literature is reviewed frequently to assure all effectiveness assumptions in the software are up-to-date.
The “Data Quality in LiST” webinar provides an overview of data sources and related issues.
